In the test summary column “FCC Rules,” the Part 2.1055/Part 95.621 lists the Frequency Stability deviation at < 5ppm. It should be 2.5ppm. The EUT was tested according to the rules of Part 95.621 at 2.5ppm. See Test Report Section 9 for compliance with the rules. Sincerely, Frank (for) Sid Sanders

- 1 - CIRCUIT DESCRIPTION Model: FRS14-SPR Aug 20,02 1. RECEIVER SECTION Radio Frequency signal received by the antenna (ANT1), passing through the Low Pass Filter (L1,L3, C2-C5). The RF signal is then amplified by Low Noise Amplifier Q1 and passes through a Band Pass Filter of L16,17,C94,96,97,82,83 (FL1 = 465MHz). The filtered signal within the range of 462 MHz – 467 MHz is then mixed with the first local oscillator signal from the Voltage Controlled Oscillator (VCO) circuit (Q16,Q10, D7, L18) through Q3, a portion of VCO signal is then feedback to the PLL IC (IC2) for phase comparison generating a stable RX frequency, the output signal is filtered by FL2 (10.7 MHz) which is the first Intermediate Frequency (IF) and is then amplified by Q4. The IF signal is fed to the discriminator IC1 pin 16 which is then mixed with the second local oscillator supplied by crystal X1 (11.15 MHz) to produced a reduced second IF signal which is then filtered by FL3 (LTM450HUT). Demodulated signal is recovered through correct adjustment of IF tank coil (IFT1) and the internal discriminator circuit of IC1. The recovered Audio signal is outputted at pin 9 of IC1 and then processed through filtering done by R10,C34, the fully recovered audio signal is then further amplified by Power Amplifier IC109. An audible sound is therefore produce by the speaker SPK100, which can be varied digitally from the CPU pins 24,25 and the corresponding series of resistors R4,R16. 2. TRANSMITTER SECTION PTT switch (SW1) when pushed triggers the Transmitter Circuit “ON”, the voice signal generates by the surrounding noise passes through the microphone MIC100 where mechanical to electrical transformation occurs, the electrical transformed signal is then filtered by Q18. The output signal is Modulated by a modulator circuit with a varactor diode D7 and L18. The external components from Q10,Q16 form a VCO Circuit which generates the required oscillating frequency for transmission, a portion of this signal is feedback to the PLL IC2 pin 14 for phase comparison in order to produce a stabilized TX frequency. The modulated signal is then amplified by a Cascaded Amplifier Circuit Q7 and Q8 and again amplified by Q5 and Q6 to produce a sufficient Radio Frequency signal emitted by the Antenna (ANT1). 3. CALL TRANSMISSION By pushing the CALL key, a signal is detected by the CPU (IC104), a CALL data is then produced by the CPU. This data passes through the Low Pass Filter Q18 and modulated by the varactor diode D7 and L18. The signal follows it’s conventional transmission section path through the antenna. - 2 - 4. BATTERY LOW DETECTION Battery Low Detection is controlled by the CPU pin 11 as detected on the LCD 1, however a voltage divider circuit R65 and R60 serve as the stabilize reference voltage for the CPU to process its detection. 5. SQUELCH DETECTION Supported by the linear IC circuit (IC1), a resistor R21 sets the level of detection and Diode D3 acts as a comparator circuit interface with the CPU. 6. POWER SUPPLY Supply voltage of 6 Volts dc is needed to power “ON” the whole circuitry, by four (4) batteries “AAA” size.
